The length of a side of the original square is about 12 inches.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the length of the original square, hence:

Area = x * x = x²

When the area is doubled:

2x² = (x + 6)(x + 4)

x² + 10x + 24 = 2x²

x² - 10x - 24 = 0

x = 12 inches

The length of a side of the original square is about 12 inches.
